This can result in the formation of blood clots that can spread to various parts of the body like the legs and lungs or raise your risk of suffering from a stroke.
Moreover, apixaban is also approved as a cure for several kinds of blood clots such as pulmonary embolus-PE and deep vein thrombosis-DVT, and stop them from developing again. Generally, Eliquis is considered as an anticoagulant that operates by preventing specific clotting proteins found in your blood.
Information for side effects includes easy bruising, nausea, or risk of bleeding – like bleeding from cuts or nosebleed. In case any of these continue and get worse, go to your doctor for medical advice and help immediately.
Take note that if your doctor or physician prescribed you with Eliquis, he/she knows that the benefit you will get from the prescription medication is far more significant compared to the risk of side effects. Most people who utilize this don’t suffer from any severe side effects.
Eliquis can result in prolonged and unusual bleeding if it dramatically impacts the protein responsible for your clotting.
Go to your doctor right away if you’ve seen signs of severe bleeding such as:
- abnormal bruising
- frequent/persistent nosebleeds
- prolonged bleeding from gums or cuts
- abnormally prolonged/heavy menstrual flow
- coughing up blood
- dark/pink urine
- unusual/persistent weakness or tiredness
- black, bloody, or tarry stools
- vomit that is bloody or looks like coffee grounds
- difficulty swallowing
Seek immediate medical advice or help if you experienced any of the cues of extremely severe bleeding, such as:
- vision changes
- slurred speech
- joint pain on one part of the body
An extremely severe allergic reaction to Eliquis is one of the rare side effects of the medication. But, you need to seek prompt medical help whenever you notice any signs of a severe allergic reaction such as:
- skin rash, swelling or itching in the throat, tongue, or face
- severe dizziness
- problem breathing or wheezing
This isn’t the full information about the potential side effects of Eliquis. It is still better to go to your physician or doctor for medical advice and information about the side effects of the said prescription medication. If you happen to experience these effects, get immediate medical assistance.
Indication And Dosage
Eliquis is used to decrease the risk of systematic embolism or stroke among patients who have non-valvular atrial defibrillation or AF.
It is prescribed as a treatment for Prophylaxis of deep vein thrombosis or DVT, which might result in pulmonary embolism or PE among patients who went through hip or knee replacement surgery. It is also used to decrease the risk of recurrent PE and DVT after initial therapy.
Eliquis is in tablet form, and it comes in two strengths: 5 mg and 2.5 mg. Here’s the proper dosage information when taking the medication.
To stop stroke and systematic embolism among patients with nonvalvular fibrillation, take 5 mg PO BID. For renal impairment or nonvalvular atrial fibrillation:
- Mild-to-moderate – no required dosage adjustment
- Serum creatinine ≥1.5 mg/dL – reduce dosage to 2.5 mg BID in case the patient has one extra characteristic of age ≥80 years or weight ≤60 kg
- ESRD maintained on hemodialysis – 5 mg BID; reduce dose to 2.5 mg BID in case of 1 additional feature of age ≥80 years or weight ≤60 kg is present
Postoperative Prophylaxis of DVT/PE
Prescribed right after a hip or knee replacement surgery.
- Initial – The patient must take 2.5 mg PO 12-24 hours before replacement surgery.
- Duration of therapy (knee replacement) – patient must take 2.5 mg PO BI for 12 days straight
- Duration of treatment (hip replacement) – patient must take 2.5 mg PO BI for 35 days straight
- The renal impairment that comes with ESRD on dialysis:
- Deep Vein Thrombosis – no recommended dose adjustment; no clinical trials or studies regarding ESRD on dialysis or patients that have CrCl <15 mL/min; dosage requirements according to pharmacodynamic and pharmacokinetic (anti-FXa activity) information acquired in study subjects with ESRD maintained on dialysis
PE or DVT Treatment
Intended for treating pulmonary embolism or PE and deep venous thrombosis or DVT. 10 mg PO BID for seven days, then 5 mg BID after.
Decrease the risk for recurrent PE or DVT:
- 2.5 mg PO BID – indicated to decrease the risk of recurrent PE or DVT right after the first six months of treatment for PE or DVT.
Renal impairment with ESRD:
- Deep Vein Thrombosis – no recommended dose adjustment; no clinical trials or studies regarding ESRD on dialysis or patients that have CrCl <15 mL/min; dosage requirements according to pharmacodynamic and pharmacokinetic (anti-FXa activity) information acquired in study subjects with ESRD maintained on dialysis.
Taken with dual inhibitors of P-GP and CYP3A4:
- If the patient is consuming 2.5 PO BID, reduce the dosage by 50%.
- If the patient is consuming 2.5 mg BID, don’t take it with potent dual inhibitors
Nonvalvular atrial fibrillation:
- Reduce dosage to 2.5 mg PO BID if patients have any of the two characteristics: at least 80 years of age and at least 60 kg of weight.
- Serum creatinine – 1.5 mg/dL
- Mild – doesn’t require any dosage modification
- Moderate – patients may suffer from intrinsic coagulation abnormalities; pieces of evidence are limited, and recommendations are lacking
- Severe – not recommended
If you trade between Eliquis and anticoagulants aside from warfarin, stop using the one being consumed, and start the other at the incoming scheduled dosage. On the other hand, if you switch from warfarin and is now taking Eliquis, stop using warfarin and see to it that you initiate Eliquis when INR <2.0.
Trading from Eliquis to warfarin:
- Eliquis impacts INR. That’s why accurate measurements when using it together with warfarin, may not tell the proper warfarin dosage.
- If your doctor or physician prescribes that consuming both medications is necessary, stop using Eliquis and start taking both warfarin and a parenteral anticoagulant at the scheduled dosage for Eliquis.
- Stop using parental anticoagulants if INR reaches the right level.
Procedures or surgery:
- Stop taking for at least 48 hours before invasive procedures or elective surgery with a high or moderate risk of abnormal or clinically relevant bleeding.
- Stop taking for at least 24 hours before invasive procedures or elective surgery with low risk of abnormal bleeding or in case the bleeding would take place in a non-critical and easily controlled area.
These medications should not be taken together with Eliquis since it could result in drug interaction, which alters how each drug works in the body. Talk to your healthcare professional, for example, a pharmacist or doctor, for more comprehensive information.
- antithrombin alfa
- Factor X, human
- mefenamic acid
- ibuprofen IV
- protein C concentrate
Severe side effects may be experienced with the following:
- fish oil triglycerides
- saw palmetto
The medicine is expected to have modest effects when taken with clarithromycin. To know more information about this, talk to your doctor or medical care provider.
Warnings and Precautions
Eliquis side effects like bleeding can occur when the meds are taken longer than intended, or the patients receive a dose more than what was prescribed. It is intended for short-term use only and under strict medical supervision. Do not ignore signs and symptoms, unusually heavy bleeding.

Apixaban is also contraindicated for utilization by patients that have extreme sensitivity to the medication. Be warned of the following contraindications when taking Apixaban.
- Bleeding – Apixaban is contraindicated among patients with present pathological bleeding since the use of this medication heightens the risk of bleeding and can result in severe and potentially dangerous bleeding.
- Abrupt discontinuation – avoid sudden stoppage of using Apixaban without sufficient alternative anticoagulation. Stopping Apixaban places patients at a higher risk of thrombotic circumstances. Increased stroke was also discovered among patients who switch from apixaban to warfarin.
- Prosthetic heart valves – the utilization of apixaban among patients who are diagnosed with prosthetic heart valves doesn’t have any clinical trials or studies yet. However, the usage of this drug among this group of patients is not suggested.
- Surgery – the anticoagulant impact of apixaban lasts for approximately 24 hours right after the last dosage. Stop using apixaban 48 hours before invasive producers or elective surgery. Bleeding is a risk with this kind of medication.
Factor Xa inhibitor restricts platelet activation by reversibly impeding the current location of factor Xa without allowing a cofactor, such as an antithrombin III since the activity prevents clot-bound and free factor Xa, as well as prothrombinase activity. It doesn’t have any direct impact on platelet aggregation. Yet, it indirectly prevents platelet aggregation caused by thrombin extrinsic and intrinsic passages that play a vital role in terms of blood coagulation flume.

Children shouldn’t consume sildenafil unless the doctor decides that it is the most suitable and effective medication to cure the child’s health complications. Viagra or Sildenafil belongs to the category of drugs that are known as phosphodiesterase (PDE) inhibitors. It treats erectile dysfunction by improving blood pressure towards the penis during sexual stimulation. With this, blood pressure is increased, resulting in a better erection. Besides, Sildenafil cures PAH by calming the blood vessels located in the lungs to enable blood to flow smoothly.
Always keep in mind that if you are consuming sildenafil to cure erectile dysfunction, it doesn’t treat erectile dysfunction nor improve sex drive. It only helps men achieve a better erection by increasing blood flow to the penis with the help of sexual stimulation. Sildenafil doesn’t prevent pregnancy nor transmit sexually transmitted diseases like human immunodeficiency virus (HIV).
Just like any medications, Sildenafil effects can also be severe or serious. If you experience any of these adverse reactions, call your doctor right away:
- flushing (feeling of warmth)
- difficulty falling asleep or staying asleep
- muscle aches
- sensitivity to light
- burning, numbness, or tingling in the arms, feet, hands, or legs
- changes in color vision (seeing a blue tone on objects or having a problem telling the difference between green and blue)
There are also Sildenafil adverse effects that can be severe. In the events that you suffer from any of the following adverse facts, call your doctor, or get emergency help right away:
- blurred vision
- sudden severe loss of vision (see below for more information)
- sudden loss of hearing
- dizziness or lightheadedness
- ringing in ears
- chest pain
- worsening shortness of breath
- the erection that is painful or lasts longer than 4 hours
- heart failure
- itching or burning during urination
Some people experience chest pain, a sudden loss of all or some of their vision right after they consume sildenafil or other prescription medications. There are rare cases that vision loss or blurred vision was permanent. However, there are still no reported studies or clinical trials that proved that the sudden vision loss was due to Viagra. If you have abrupt vision loss while taking Viagra, contact your doctor or physician right away. Discontinue using any more dosages of Viagra, Sildenafil or other similar medications like vardenafil (Levitra) or tadalafil (Cialis) until you reach out to your doctor.
Besides this, adverse reactions such as stroke, high blood pressure, irregular heartbeat, coronary artery disease, bleeding in the lungs or brain, and sudden death among men who consumed Sildenafil to treat erectile dysfunction. The majority of these people, but not all, suffered from heart complications before drinking Viagra. It is still unknown if these circumstances were due to Viagra, heart failure, sexual intercourse, or a combination of all of these. This is because there are no studies and clinical trials reported that link Viagra into all of these. Talk to your physician or doctor about the adverse reactions of Viagra before taking it.
Furthermore, some individuals suffer from abrupt loss or decrease of hearing right after they consumed sildenafil (Viagra) or any other medications that are associated with Sildenafil. Usually, the hearing loss from Sildenafil only affects one ear and doesn’t always progress once the patient discontinues taking medicine.
It is still unknown whether the sudden hearing loss was due to Viagra since there are no clinical trials and studies that prove it. In the events that you experience abrupt hearing loss, alongside dizziness or ringing in the ears, while you are drinking Viagra or Sildenafil, contact your doctor right away. Always remember that if you are consuming Viagra, Sildenafil, and any other medications such as vardenafil (Levitra) or tadalafil (Cialis) to treat erectile dysfunction, don’t take more dosages unless your doctor says so.
On another note, if you are consuming Revatio Sildenafil to treat PAH, never discontinue your usage until you discuss it with your physician or doctor. Viagra or Sildenafil may also cause other forms of adverse reactions. So if you experience unusual symptoms while consuming Sildenafil, talk to your doctor right away. In case you experience any severe side effect, your doctor, physician, or you could send a report to the Food and Drug Administration’s (FDA) MedWatch Adverse Event.
